A quick release nut

Abstract

The invention relates to the technical field of fasteners, in particular to a quick-release nut, which cooperates with a screw rod, and includes a first ferrule, at least one thread block and a second ferrule arranged in sequence from bottom to top, and the upper part of the first ferrule There is a sliding groove on the end surface, and the sliding groove is slidingly matched with the limit slider provided on the outside of the threaded block, and the inner thread is provided on the inner side of the threaded block, which is screwed and matched with the external thread of the screw, and the limit slider is connected with the guide , the guide piece is slidingly matched with the equal-width arc groove in the second ferrule. There is an offset distance between the arc center of the arc groove and the center of the second ferrule, and the end of the arc groove close to the center of the second ferrule is tightened. At the end, the circumferential rotation of the second ferrule drives the guide and the threaded block to move radially along the sliding groove. When the guide is located at the tightening end of the arc groove, the threaded block rotates with the circumferential rotation of the second ferrule. The invention can solve the problems in the prior art that it is inconvenient to disassemble and assemble ordinary nuts, and that the quick-release nuts have complex structures and are difficult to manufacture.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a quick-release nut. Background technique [0002] At present, most of the thread locking structures use an integral nut and a screw-in structure with an external thread. To remove the nut from the screw rod during use, it must be screwed down along the screw rod, which is time-consuming and laborious. For those who require quick release and quick release It is even more inconvenient to install. [0003] Patent CN201420328738 discloses a quick-installation and quick-release nut, which uses a threaded block to move radially and axially along an inclined plane to achieve engagement and separation of the threaded block. If the thread lock is not in place, the bearing capacity and reliability are poor. Contents of the invention [0004] The purpose of the present invention is to provide a quick-release nut to solve the problems in the prior art that the ordinary nut is inconven...
